ASR-33 differences

[Marc Howard]

Hi,

I've finally gotten a hold of a restored ASR-33.  One question I have
concerns the paper tape reader.

My recollection of using this TTY in the 70's was that the reader switch
lever had 4 positions; on this tty there are 3.  I know that for I have to
add a reader control relay to interface to my PDP-8.

So the question is: does having the 3 vs. 4 position reader lever affect
using this with a PDP-8?

Thanks,

Marc
